DVSA Adverse Weather Driving

Question 1

In wet conditions, how much longer can your overall stopping distance be compared to dry conditions?

Accepted Answer

At least double

Answer

In wet conditions, your overall stopping distance can be at least double that of dry conditions. This is because reduced tyre grip on a wet road surface increases braking distance significantly.

Question 2

What is aquaplaning?

Accepted Answer

When your tyres lose contact with the road surface due to a layer of water

Answer

Aquaplaning occurs when a layer of water builds up between the tyres and the road surface, causing the tyres to lose grip. The steering becomes very light and unresponsive.

Question 3

When should you use rear fog lights?

Accepted Answer

When visibility is seriously reduced, generally below 100 metres

Answer

Rear fog lights should only be used when visibility is seriously reduced to below 100 metres. Using them in lighter conditions dazzles drivers behind and can mask your brake lights.

Question 4

What should you do if you encounter black ice on the road?

Accepted Answer

Keep your speed steady, avoid sudden braking or steering

Answer

On black ice, you should avoid sudden braking, acceleration, or steering. Keep a steady speed and steer gently. If you start to skid, ease off the accelerator and steer into the skid.

Question 5

When driving at night, when should you dip your headlights?

Accepted Answer

When following or meeting other traffic to avoid dazzling them

Answer

You must dip your headlights when meeting oncoming vehicles and when following another vehicle, to avoid dazzling their driver through their mirrors.
